Mathematics for IGCSE & O level - Pythagoras' Theorem And Trigonometry (Section 7 - No. 27)
Which of the following is the Sine Rule?
a² = b² + c² - 2bc cos A
sin A / a = sin B / b = sin C / c
a/sin A = b/sin B = c/sin C
tan θ = Opposite / Adjacent
Објашњење
The correct statement of the Sine Rule is a/sin A = b/sin B = c/sin C.
